SIGN.

SPECIFICATION forming part of Letters Patent No. 608,963, dated August 9, 1898. Application filed December 30, 1895. serial No. 578,721. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM HEEREN, a citizen of the United States of America, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a certain new and useful Improvementin Signs, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain new and useful improvements in signs, and has for its object to apply a filling of celluloid as an ornament or distinctive filling within the apertures of a metallic or other receiving base, as hereinafter described, and particularly pointed out in the claim.

In describing the invention in detail reference is had to the accompanyingdrawings, forming a part of this specification,and wherein like figures of reference indicate similar parts throughout the several views,inwhich Figure 1 is a front View of my improved sign. Fig. 2 is a back View of the same. Fig. 3 is a vertical sectional view showing manner of applying the celluloid.

Referring to the drawings, 1 designates the body of the sign, which is made of metal or any suitable material and has an opening 2 stamped or cut through the body of the sign. Said opening may be of any design. In the present instance I have shown the letter C.

Placed over the opening 2 is asheet of celluloid 3, conforming in general outline to the letter and slightly larger than the opening. On the top of the celluloid I place a sheet of suitable pliable materialhsuch as lead or pasteboard, said pliable material forming a yielding anvil-die. This sheet 4 is some what larger than the sheet of celluloid. The pile so formed is then placed upon a highlypolished heated block 5, as shown in Fig. 3. The celluloid, being rendered plastic by the action of the heat, is pressed into the opening 2 by the pliable material when force is applied thereto by the plate 6. The heat not only renders the celluloid plastic,but the surface of the celluloid projecting into the opening and into contact with the heated block is given a high polish and also completely fills the opening and makes an even surface. 7

In constructing signs and the like as above described (the substitution of celluloid for enamel) the sign is more durable, retains the highly-polished surface, and is not afiected by the weather, as is the case where enamel is used. Furthermore, any color of celluloid may be used, and an artistic finish is given to celluloid which cannot be accomplished with enamel. Furthermore, in constructing designs representing flowers, leaves, and the like the celluloid can be coated on the :rear face, so as to present an exact representation of the design intended.

I do not limit myself to sign-lettersand signs, but desire to employ this construction in all similar class of work.

Having fully described my invention, what I claim as new, and desireto secure by Letters Patent, is-- The process of forming imitation signs, badges and the like, comprising the following steps, to wit: first, punching or otherwise cutting through the sign-plate the particular design intended; second, positioning upon said apertured sign-plate a celluloid wafer; third, placing upon said wafer a yielding anvil-die fourth, placing a highly-polished block to the face of the sign-plate, and applying heat to said block whereby said celluloid wafer is rendered pliable, then applying pressure to the back of the yielding anvil-die and forcing thepliable celluloid into said apertures until the same is brought into contact with the heated block, thereby producing a highlypolished face on the celluloid filling of said apertures, substantially as shown and described.

In testimony whereof I affix signature in presence of two witnesses.

WILLIAM I-IEEREN.
